Abstract

The invention relates to an axial flow water turbine with an ocean power generation function. The axial flow water turbine is characterized by comprising a water inlet section (4-1), an upper guide vane (4-2), a runner (4-3), a lower guide vane (4-4) and a water outlet section (4-5), wherein the upper guide vane (4-2) is arranged between the water inlet section (4-1) and the runner (4-3), and the lower guide vane (4-4) is arranged between the runner (4-3) and the water outlet section (4-5); the opening degrees of the upper guide vane (4-2) and the lower guide vane (4-4) are controlled by an intelligent guide vane opening degree controller (7), and the intelligent guide vane opening degree controller (7) regulates the opening degrees of the guide vanes automatically according to the flow flowing through the water turbine and the head condition, so that the water turbine outputs the highest power and has the highest efficiency. The axial flow water turbine has the remarkable effects of low requirement for the head, long effective working time, good stability and the like and can replace various conventional overtopping type wave power generation devices.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery and water conservancy and hydropower engineering equipment, and in particular relates to an axial-flow water turbine which utilizes ocean energy to generate electricity. Background technique [0002] Traditional energy sources are about to be exhausted and have brought about serious environmental problems, and it is urgent to find and develop alternative new energy sources. The world's oceans are rich in resources, and the waves contain huge energy. The use of ocean waves to generate electricity does not require fuel and has little impact on the environment, so it has great development and utilization value. [0003] Chinese patent application 201320442966.1 "Offshore Oscillating Water Column Power Generation Device" discloses an offshore type oscillating water column power generation device that can float anywhere in the water to generate electricity using waves. Entering the air chambe...
